Said in advance: for about three months this pan several times a week in use. So far, signs of usage have not shown on the coating still has the pan bottom bent, he is still as flat as the first day. One should here but watch out for when Tefal there are pans with different "hardness", therefore can not be inferred from a pan of Serie A on a model from series B.
I give this product finally only 4 out of 5 stars, although me this product actually fits perfectly. However, there are two weak points, although for me are of no great importance, but could be very important for other buyers might.
1) The so-called thermo-spot in the center is indeed a great idea, but in practice this does not work for me. If I heat oil in the pan and would read the temperature / estimate, then I must always switch on the lights on the hobs. Indirect sunlight is not enough in my kitchen that is in order to determine the status of the warming can. Conclusion: a good idea, but a useless feature for me, because the various red tones of the circle are not different enough to be clearly visible.
Although 2) The flat lid matches the pan, but the integrated steam opening VERY VERY is really bad solved. Honestly, such a stupid design I've never seen. Even if you tend to cover only about 10 or 15 degrees in the wrong direction, opens or closes the vapor opening with an annoying rattling of itself. Can really use to this function only if the lid can remain truly flat on the pan and the pan all the time is unchanged on a flat surface. Any other movement - whether you're the cover decreases briefly and turns off somewhere, or if you take the pan from the plate - and you can hear how the slider moves the steam hole. I have luckily enough another cover, because at this Tefal pan also seem generic 24cm lid fit well, so the dust enclosed cover since the first week in the closet.
